General Information for Transportation, Unpacking and Storage

-This valve is not designed to handle impacts of any kind. Avoid throwing or dropping the valve.
-Avoid scratching the valve with any sharp object.
Caution
-Do not over-stack cardboard shipping boxes. Excessively stacked packages may collapse.
-Avoid contact with any coal tar creosote, insecticides, vermicides or paint.
(These chemicals may cause damage to the valve.)
-Store products in their corrugated cardboard boxes. Avoid exposing products to direct sunlight, and store them
indoors (at room temperature). Also avoid storing products in areas with excessive temperatures. (Corrugated
cardboard packages become weaker as they become wet with water or other liquid. Take care in storage and
handling.)
-After unpacking the products, check that they are defect-free and meet the specifications.

Inspection Items

Check for flaw, crack, or deformation on the valve.
Caution
Inspect the cap nut and be sure it is not loose.
General Operating Instructions
-Certain liquid such as H
which may destroy the valve.
Warning
-Do not change or replace the Y-SEDIMENT STRAINER parts under line pressure.
-Using a positive-pressure gas with our plastic piping may pose a dangerous condition due to the repellent force
particular to compressible fluids even when the gas is under similar pressures used for liquids. Therefore, be sure
to take the necessary safety precautions such as covering the piping with protective material. For inquiries, please
contact us. For conducting a leak test on newly installed piping, be sure to check for leaks under water pressure.
If absolutely necessary to use a gas in testing, please consult your nearest service station beforehand.
-Be sure to conduct a safety check on all hand and power tools to be used before beginning work.
-Wear protective gloves and safety goggles as fluid remain in the valve even if the pipeline is empty. (You may be injured.)
-Do not step on or apply excessive weight on valve. (It can be damaged.)
-When installing a pipe support by means of a U-band or something similar, take care not to over-tighten. (Excessive

force may damage the pipe.)
-Take care not to over-tighten the Union Nut. (The valve can be damaged.)
-Keep the valve away from excessive heat or fire. (It can be damaged, or destroyed.)
-Always operate the valve within the pressure vs. temperature range.
(The valve can be damaged or deformed by operating beyond the allowable range.)
